Investigators say the crash happened after a white car that was parked in a moving lane of traffic, swerved into the fire department's vehicle, hit it and caused that car to lose control.

Eyewitnesses at the scene say the pedestrian had just finished lunch at a nearby soup kitchen. They say he was sitting along a concrete wall on Jensen when the fire department's non-emergency vehicle, hopped the curb and landed on top the victim, crushing him.

We spoke with one man who says he witnessed his friend's death.

"The car hit my friend. He just say 'Hi Gino,' I said hi. And when he put his hand like that, the car hit him -- boom -- and he was under the car," witness Franp "Gino" Huyn said.

Hyunh says he and other witnesses rushed to try rescuing the victim who was pinned under the car.

"We tried to pull the car up. To take the person out. They still leave the person under. But they don't care, they take a call. They don't care about what the person under the car," he said.

The fire department is not releasing the name of the employee involved, nor tell us in what capacity he works at this time. We're told he suffered minor injuries from an airbag and is devastated about what happened.

Several agencies are investigating the wreck right now, but police say it appears the driver of the white car is at fault and will likely be issued a citation.
